[Kamailio-Users] ACK without matching transaction discarded

[Daniel-Constantin Mierla]

Hello,

seems are you doing record_route()/loose_route() processing, right? You 
need to change the scenario of the sipp to handle the Record-Route 
headers. The ACK should arrive to kamailio with a Route header.

Cheers,
Daniel
